Dating someone completely different

It’s been 5 years since my last relationship now I’m starting dating someone who’s really kind and gentle but we’re so different from each other he said that he doesn’t mind our differences but I can’t help but to notice that we don’t have anything in common

I mean except our feelings I like him he like me but our interests are so different

I meant isn’t dating suppose to be finding someone who shares a lot with you ...etc 😢
